ROLLER-SKATE.

SIPECIPICATION forming part of Letters Patent No. 332,049, dated December 8, 1885.

A Applicatibn filed July 27, 1885. Serial No. 172.735. (No model.)

To all whom it may concern.-

Be it known that I, MARTIN BYE, a citizen of the United States, residing at Worcester, in the county of WVorcester and State of Massachusetts, have invented certain new and use ful Improvements in Roller-Skates; and I do hereby declare that the following is a full, clear, and exact description thereof, which, in connection with the drawings making a part of this specification, will enable others skilled in the art to which my invention belongs to make and use the same.

My invention relates to roller-skates; and it consists in certain novel features of construction of the roller frames or trucks, as will be hereinafter fully described, and the nature thereof indicated by the claims.

Referring to the drawings, Figure 1 is a side elevation of a roller-skate embodying my invention, one of the rollers being removed. Fig. 2 is a central longitudinal section through the front roller frame or truck and part of the foot-plate shown in Fig. 1, the dotted lines representing a turning-key for regulating the rocking motion, as will be hereinafter described. Fig. 3 is a top or plan view of the roller frame or truck shown in section in Fig. 2, the foot-plate and turning-key being removed.

In the accompanying drawings, the part marked A is the foot-plate of the skate, provided in this instance with a hole, a, at each end extending through it, for the purpose to be hereinafter described.

The straps for securing the foot-plate A to the foot of the wearer are not shown in the drawings, as they are of the usual construction and operation, and form no part of my present invention.

B is the bracket, made in substantially the shape and of the construction shown in the drawings, having screw-holes b 12 therein for securing the bracketB to the under side of the foot-plate A, as shown, by means of screws 0 c. The bracket B has an opening or hole, d, in its upper part, and also a slot or opening, 6, in its lower part. The bottom side of the bracket B is made rounded or convex.

G is the hanger or truck, which carries the axle f, on which the rollers D are placed. The top side of said hanger O is made rounded to correspond with the bottom side of the bracket B, and so that the hanger can rock from side to side. The upper part or point, 9, of the hanger 0 projects into the opening or hole d in the bracket B, thus serving to support the hanger O in connection with a threaded stud or pin, h, projecting up from the top side of the hanger C, and extending through the slot or opening 6 in the bracket B, as clearly shown in Fig. 2. Said pin or stud h may be made integral with the bracket 0 or separate therefrom and secured thereto by fitting or being driven into a hole therein. A spring, i, preferably made of coiled wire, encircles the pin h, and is inclosed in a case, j, which preserves the shape of the spring 2' and prevents lateral distortion. The case j is provided with ahole in its bottom, through which the stud h passes. It is also provided with a little knob or projection, h, extending from the bottom thereof, which extends into the slot e in the bracket B, for the purpose of preventing the casej from turning around. Afollower, Z, with athreaded hole through its center to receive the threaded stud or pin h, and, in connection with the spring 2', to secure said stud h and the hanger O to the bracket B, is made to close the mouth or top of the case j and to hold the coiled spring 1' in place. The follower Z has in this instance two small holes,hh,in its upper surface, for the purpose of receiving the projecting ends of the turning-key E, which is passed through the hole a in the foot-plate A, and by means of which the follower Z is turned in or out in the case j on the stud or pin h to tighten or loosen the spring i, held and contained within said case, allowing the hanger O to rock more easily or less easily, as may be desired by the person using the skate.

By my improved construction of the roller frame or truck, as described, and shown in the drawings, the spring which draws the hanger 0 back into its normal position after it has been rocked in either direction is inclosed in a separate case, which confines and holds said spring in place, preventing it from bulging out in any direction and becoming laterally distorted, thus always causing it to operate in the proper manner, and to bring back the hanger G into its normal position after it has been rocked on its supporting-bracket B to allow of the wearer turning curves.

The degree of force or strength required to move or rock the hangers O of the skate may be regulated as desired,according to the weight of the person Wearing the skate, by simply inserting the turning-key E through a hole in the foot-plate of the skate and fitting it into the holes an in the follower 7, and turning said follower on the threaded pin or stud h in one direction or the other, according to Whether the tension of the spring 13 is to be increased or diminished.

Having described my improvements in roller-skates, what I claim therein as new and of my invention, and desire to secure by Letters Patent, is

1. In a roller-skate, a truck or frame composed of the bracket 13, hanger 0, provided with the pin or stud h, the case j, spring 1', and

follower Z, combined together substantially as described and shown.

2. In aroller-ska-te truck or frame, the combination, with the bracket B, case j, and spring 2', of the hanger 0, provided with a threaded stud or pin, it, and the follower Z, substantially as set forth, and for the purpose stated.

3. In a roller skate truck or frame, the bracket B, case j, and spring i, in combina-' tion with the hanger O, threaded pin or stud h, follower Z, and means for regulating the ten sion of the spring 2', substantially as set forth, and for the purpose stated.

, MARTIN BYE.
